<p>A final state is used to communicate that (part of) a <a href="qstatemachine.html">QStateMachine</a> has finished its work. When
a final top-level state is entered, the state machine's <a href="qstate.html#finished">finished</a>() signal is emitted. In
general, when a final substate (a child of a <a href="qstate.html">QState</a>) is entered, the parent state's <a href="qstate.html#finished">finished</a>() signal is emitted.
QFinalState is part of <a href="statemachine-api.html">The State
Machine Framework</a>.</p>
<p>To use a final state, you create a QFinalState object and add a
transition to it from another state. Example:</p>
<pre class="cpp">
 <span class="type"><a href="qpushbutton.html">QPushButton</a></span> button;

 <span class="type"><a href="qstatemachine.html">QStateMachine</a></span> machine;
 <span class="type"><a href="qstate.html">QState</a></span> <span class="operator">*</span>s1 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qstate.html">QState</a></span>();
